  • Varactor voltage controlled oscillator (VCO) providing independent coarse and fine frequency tuning
    Patent number: 8786376
    Abstract: A voltage controlled oscillator, includes a tank circuit including an inductor having a value L, interconnected with first and second variable capacitors, having values CVAR1 and CVAR2, and a fixed capacitor CFIXED, to cause oscillation of the oscillator at a controlled frequency f osc = ( 2 ? ? ) - 1 ? ( L ? { C VAR ? ? 2 + C FIXED ? C VAR ? ? 1 C FIXED + C VAR ? ? 1 } ) - 1 / 2 CVAR1 controls coarse frequency tuning of the oscillator, and CVAR2 may control fine tuning of the oscillator. The variable capacitors may be formed using accumulation-mode MOS varactors.

  • Radio antenna switch
    Patent number: 8676136
    Abstract: A radio antenna switch module for a high frequency radio transceiver enables the radio transceiver to have a small number of receivers and transmitters and a larger number of antennas, whereby each antenna has a different diversity characteristic. The diversity between antennas provide for greater communication reliability, while the small number of receivers and transmitters allows the transceiver to operate at relatively low power compared to conventional radio transceivers. The switch module also allows for two loopback modes between the transmitter and the receiver for at-speed, low-cost self-test in production.
